Definitions

  • the invention relates to a process for producing a two-chamber pressurized package having an outer body which encloses an interior space, which can be subjected to pressure, and forms an opening through which an inner body of a material which can fold or be crumpled is inserted.
  • two-chamber pressurized packages of this kind are today used to replace the known pressurized containers employing a propellant gas.
  • the medium is dispensed from the inner body by the subjection to pressure of the interior space of the outer body.
  • the medium to be dispensed therefore does not come into contact with this pressure medium but is forced out through a valve by alteration of the inner body.
  • These known two-chamber pressurized packages essentially comprise three parts, namely the outer body, for example an aluminum sleeve having a base, the inner body, for example a very thin aluminum sleeve and a funnel which is placed on the orifice edge of the inner and outer body and surrounds the latter sealingly. The appropriate valve is then inserted centrally in this discoid funnel.
  • the outer body for example an aluminum sleeve having a base
  • the inner body for example a very thin aluminum sleeve and a funnel which is placed on the orifice edge of the inner and outer body and surrounds the latter sealingly.
  • the appropriate valve is then inserted centrally in this discoid funnel.
  • the funnel is rolled or flanged together with the orifice edges. It therefore requires a certain space. Since the valve itself in general likewise requires a diameter of 25 mm, the openings of the present-day two-chamber pressurized packages necessarily have a total diameter of about 40-65 mm. In between, only two-chamber pressurized packages having stepped dimensions are used.
  • the inventor has set himself the object of developing a process of the type mentioned above by means of which the fitting of the additional funnel is made superfluous, in which the interior space of the outer body is kept absolutely leakproof and in which two-chamber pressurized packages having various opening diameters can be produced, starting from as low as 1 inch, i.e. 25.4 mm.
  • This object is achieved by the fact that, prior to flanging, or the like, of the opening, filling of the inner body and fitting of a valve in the region of the orifice, the outer body and inner body are connected to one another in a predetermined region and are then folded over together to form a flanged edge.
  • connection is preferably effected by welding, adhesive bonding, deformation or the like.
  • the best solution here has proved to be a coating which is applied either to the outer body or to the inner body or to both in the connecting zone prior to the insertion of the inner body into the outer body.
  • This coating for example a suitable adhesive, can then dry, so that the inner body is inserted into the outer body without any alteration to the coating.
  • the two-chamber pressurized package preferably passes through an oven, in which the coating is liquefied. A certain connection is thereby produced already between the inner body and outer body.
  • the inner body Since, however, in general, the inner body maintains a certain distance from the outer body so that, in the use position, it can be surrounded by sufficient pressure medium, it has proved to be advisable to introduce a tool into the opening of the two-chamber pressurized package, via which tool the inner body is pressed against the outer body in the appropriate connecting zone.
  • This tool can be heated in order that the liquefaction of the coating may be effected or maintained by means of this heat.
  • the orifice edges are then flanged, this preferably being accomplished by rolling.
  • the inner space is henceforth absolutely leakproof. If leaks should occur, contrary to expectations, in the region of the connection, additional sealing material can be introduced through the opening which also serves for the subjection to pressure of the inner space, which then flows along the inner walls of the outer body and thus supplements the coating of the connecting zone.
  • a sealing compound covers the area of the flanged edge in which the folded edge contacts the inner surface of the inner body or lies partly on the inner body.
  • the sealing compound is exposed to the inner pressure of the two-chamber pressurized package so that the cutting edges are absolutely isolated and the space between the outer body and the inner body is sealed.
  • the inwardly folding of the flanged edge has the important advantage that the contact height and the height of the pressurized package can be determined more exactly. It is not necessary to mill the outer sealing surface.
  • FIG. 1 shows a longitudinal section through a two-chamber pressurized package in accordance with the invention in a preliminary stage of production
  • FIG. 2 shows another longitudinal section through the two-chamber pressurized package according to FIG. 1 at a further stage of production
  • FIG. 3 shows a longitudinal section through a further embodiment of a two-chamber pressurized package according to the present invention in a stage of the production according to FIG. 2;
  • FIG. 4 shows an enlarged cross-section through the area of the flanged edge for the embodiment of FIG. 3.
  • a two-chamber pressurized package P in accordance with the invention has a sleeve-shaped outer body 1 which, in the present exemplary embodiment, essentially comprises a cylindrical jacket 2 and a base cover 3.
  • This outer body 1 can be produced, for example, by extrusion or deep drawing from a circular aluminum blank.
  • the base cover 3 has a bore 4, via which the interior space I can be put under pressure. After this procedure, the bore 4 can be sealed.
  • An inner body 6 is inserted into a cylindrical opening 5 on the side opposite the base cover 3 of the outer body 1.
  • This inner body 6 likewise has a cylindrical jacket 7 and has a continuous base cover 8.
  • this inner body 6 consists of a relatively thin aluminum, with the result that it can be crumpled with the formation of folds.
  • Cylindrical jacket 7 and base cover 8 surround a space R which, in the use position, serves to accommodate a medium to be dispensed.
  • the inner body 6 maintains a distance a from the cylindrical jacket 2 of the outer body 1 over extensive areas. However, toward the cylinder opening 5, i.e. in the region of the orifice of outer body 1 and inner body 6, the inner body 6 or its cylindrical jacket 7 is connected in region b to the cylindrical jacket 2.
  • the connection is effected, for example, by welding, adhesive bonding, laser welding, deformation or the like.
  • the outer body 1 is drawn from a circular aluminum blank.
  • the bore 4 is introduced into the base 3 and the cylindrical jacket 2 is provided over the region b with a coating 9 of an adhesive or welded.
  • the inner body 6 is then inserted, the coating 9 having solidified, with the result that it does not hinder insertion.
  • the two-chamber pressurized package P now passes through an oven, in which the coating 9 is liquefied. As a result, a connection between cylindrical jacket 2 and cylindrical jacket 7 is initiated even at this stage. However, the connection proper is produced by a heated tool, which is introduced through the cylinder opening 5 and presses the cylindrical jacket 7 against the cylindrical jacket 2 in the region b.
  • the next processing stage is shown in FIG. 2. Firstly in this processing stage, the base cover 3 is deformed, so that it can withstand an internal pressure in the interior space I and does not curve outwards.
  • Cylindrical jacket 2 and cylindrical jacket 7 are furthermore flanged outwards in the region of the cylinder opening 5, thus producing a flanged edge 10. During this procedure, cylindrical jacket 2 and cylindrical jacket 7 are simultaneously drawn inwards in a certain region.
  • the space R of the inner body 6 is now filled with the substance to be dispensed and the cylinder opening 5 is closed by means of a cover (not shown) with a valve.
  • This cover seals the flanged edge 10.
  • the interior space I of the outer body 1 is then put under pressure via the bore 4, whereupon the bore 4 is sealed.
  • the inner body 6 is put under pressure, with the result that when the valve is actuated the medium is dispensed from the space R of the inner body 6 through the valve, while the inner body 6 yields to the same extent to the pressure in the interior space of the outer body 1 and crumples.
  • the flanged edge 10a is folded inwardly.
  • the cutting edges 11 and 12 of the outer body 1 and the inner body 6 shown schematically in FIG. 4 are hidden so that no corrosion arises on the cutting edges.
  • a sealing compound 13 is filled in the area of the contact of the outer body 1 and the inner body 6 in the inside R of the container.
  • the space R is filled with pressure and this pressure presses the sealing compound 13 in the said area against the inner body 6 and the outer body 1 so that the cutting edges 11 and 12 and also the space between the outer body 1 and the inner body 6 are absolutely isolated.
